[2] He served as Provo Daily Herald columnist and Washington journalist before "seeing the light"[3] and starting work in 1993 as a correspondent, researcher, and senior editor for The New American, the official biweekly magazine of the John Birch Society (JBS).
Based at the JBS's office in Appleton, Wisconsin, Grigg covered United Nations summits and conferences from 1994 to 2001, and wrote Freedom on the Altar (1995), a study of UN family policy.
[2] Associate Kevin Bearly, a minister and former police officer, conducted JBS summer youth camps in the 1990s at which Grigg and others promoted conservative causes.
Grigg was associate director for Activate Congress To Improve Our Nation (ACTION), a committee incorporated by JBS to promote the impeachment of President Bill Clinton, with chapters in 50 states.
His New American article "Revolution in America", a study of immigration problems and issues, was reprinted for its "current and incisive" rhetorical qualities by a McGraw-Hill college text.
[2][verify] Grigg has promoted the concept that "white Leninists" desired to send "millions of Mexicans across the border with the idea of having each kill 10 Americans".
Grigg was also a studio and live musician[1][verify] who served as lead guitarist in the Wisconsin band Slick Willie and the Calzones, until his 2005 move to Idaho.
